Description
Non-perturbative lattice QCD calculations at non-vanishing baryon
number density are hampered by the sign problem. The path
integral becomes highly oscillating and standard Monte Carlo techniques
seize working. One possible solution is the Lefschetz thimble
approach. It requires a deformation of the original integration domain
into a manifold embedded in complex space. For properly chosen
integration manifolds (``thimbles'') the sign problem is drastically
alleviated. For some bosonic and fermionic models this approach has
been shown to work. In this talk we will discuss aspects of the
thimble discretization of low dimensional QCD.
